There are lots of repairs that one can handle around their own home without expert knowledge or with only a little bit of research. When it comes to your air conditioning system though, there are a few times when you should skip the DIY repairs call in an air conditioning expert instead.
#1: No Cold Air Coming Through the Vents
The entire purpose of your air conditioning system is to push cold air throughout your home. If you have changed the air filter and made sure that none of your ducts are covered up, and your thermostat is set correctly, and your unit is still not blowing out cold air, it is time to call in the experts.
When you take care of the basic troubleshooting, and your AC is still not blowing out cold air, you may have a mechanical issue with your unit. You may have an internal part that needs to be replaced. A professional will be able to get to the bottom of why your unit isn't blowing cold air and fix the issue right away.
#2: Something Doesn't Smell Right
The very first time you use your air conditioning at the start of the year, it may smell a little off, but that should disappear after a couple of cycles. If you have been running your air conditioning on a regular basis, and suddenly, things don't smell right, you need to take action right away. For example, if your air conditioner has an ongoing musty smell, then you may have mold somewhere in your system. An experienced technician will be able to find the mold and clean it up.
Note that if your air conditioner has a metallic or burning smell, you need to turn off your unit and call for assistance right away. A metallic or burning smell is generally a sign that the electrical wires somewhere in your air conditioning unit are burning, which could be a very serious issue.
#3: Decreased Output
If your unit is blowing out cool air but at a decreased output, you can do a little troubleshooting. Make sure the vents are covered up and are fully open. Then, make sure that the filter is clean. If the output is still down after doing all of that, call in an expert. Issues such as a dead or dying motor, as well as a loose fan belt, among other issues, can make the blower that powers your air conditioning unit not work as it should. This is something a professional will be able to easily fix for you.
If you have done basic troubleshooting, and you are getting decreased output, no cold air, or your air conditioning unit is putting out an unpleasant smell, consider contacting local air conditioning repair companies.
